4.2 Elements of the QTPI
4.2.1 General
Power plant operators shall consider the elements listed from 4.2.2 to 4.2.7 in order to maintain and continuously improve the QTPI during the operational phase. See Figure 1.
4.2.2 Initial operation capability
Initial operation capability means the ability to begin operation of thermal power infrastructure as planned and scheduled in accordance with relevant specifications and unit-specific conditions.
4.2.3 Supply stability
Supply stability means the ability of thermal power infrastructure to consistently supply electric power when required.
4.2.4 Reliability (reliable operation and fast recovery)
Reliable operation means to minimize internal forced outages of thermal power infrastructure as much as is practical and to safely deactivate the infrastructure without damaging the equipment.
Fast recovery means to recover from a forced outage as soon as is practical.
NOTE Internal forced outage refers to a shutdown or output power suppression that is within the controlof the power plant. They can be caused by external and internal incidents, excluding shutting down or limitingoutput power due to events such as planned maintenance.
4.2.5 Environmental and social considerations
Environmental and social considerations means the consideration given to the prevention or controlof environmental impacts attributable to the thermal power infrastructure and to the need to coexistwith the local community.
NOTE1 The factors that need to be considered from the viewpoint of reducing adverse environmental impactscan include, but are not limited to, the control of air pollutants, waste water, effluents, noise, other waste andGHG emissions.
NOTE2 The factors that need to be considered from the viewpoint of addressing social aspects can include,but are not limited to, community engagement, operational transparency and public disclosure. For details ofsocial considerations refer to lso 26000.
Safety means the ability to prevent injury to humans.4.2.7 LCC
LCC in the context of thermal power infrastructure means the summation of the costs incurredthroughout the life cycle of the thermal power infrastructure, provided that it satisfies all requirementsof the QTPl elements specified above.
Note that LCC can generally be classified into engineering, procurement and construction (EPC) costs,operating and maintenance costs and demolition costs, including disposal costs.In the case of a thermalpower infrastructure, fuel costs typically account for a large portion of operating costs.The LCC alsoincludes other costs such as costs caused by forced outages or the costs associated with compensationor penalties incurred as a result of failing to meet requirements for emissions or pollutants.
4.2.8 Performance indicators and evaluation of the QTPI
Power plant operators shall collect the data required for evaluation by evaluators as specified inTable 1 to ‘Table 10.Evaluators may include stakeholders such as insurance underwriters, governments,power providers,NGOs and environmental organizations. Evaluators may utilize the indicatorsshown in 4.3 for appropriate measurement of the QTPl during the operational phase of the thermalpower infrastructure. The evaluation methods and formulas shall be reviewed, as appropriate, so thatevaluations can accommodate relevant changes in requirements or circumstances.
4.3Evaluation indicators
4.3.1Supply stability Availability
Table 1 shows the evaluation method, formula, evaluation period, unit of measure and scope required toassess, at planned intervals, operation and maintenance capability of the thermal power infrastructureand the quality of unit. Changes to heat rate (HR)
Table 2 shows the evaluation method, formula, evaluation period, unit of measure and scope required to assess the change in HR of the unit or plant. Ability to adjust power supply to demand
Table 3 shows the evaluation method, formula, evaluation period, unit of measure and scope required to assess the ability of the unit to adjust output power in response to changes in demand.BS ISO 37160 pdf download.
